Kennametal 2599745 Grooving Insert NG2047 KC5010 Carbide

Product Description

The KENNAMETAL 2599745 is a solid carbide grooving insert designed for precision external grooving and parting operations on CNC lathes and turning centers. Manufactured under the Top Notch series, this insert carries a TiAlN coating applied via PVD process, which improves wear resistance and thermal stability at the cutting edge. The insert is configured for right-hand cutting with a neutral rake geometry, a cutting width of 1.19 mm, and a maximum depth of cut of 1.27 mm. It is installed and replaced by machinists and toolroom technicians maintaining turning toolholders in production or job-shop environments.

This insert is suited for grooving operations on small-diameter workpieces where tight width tolerances are critical. The NG2047 designation identifies the insert size and style within the Top Notch system, making it a direct fit for compatible Top Notch-style toolholders. Typical applications include groove width control on steel, alloy, and cast iron components. The KC5010 grade with TiAlN coating targets interrupted cuts and general-purpose turning where abrasion resistance is a priority. It is used in both production turning and maintenance machining settings.

Installation Notes

This insert is installed by qualified machinists or toolroom technicians servicing CNC or manual turning equipment. Power down and lock out the machine before changing inserts. Use the appropriate torque wrench and insert clamp hardware specified by the toolholder manufacturer — do not overtighten the clamping screw. Inspect the toolholder pocket for wear or debris before seating the new insert to ensure proper support and accurate cutting geometry.
